Claims

[Scope of Claim for Utility Model Registration] (1) A printed circuit board block equipped with a contact mechanism block that opens and closes contacts by operating a handle, a dimming section that controls the lighting load by the output of the contact mechanism block, and both of the above. A body for storing the block, a metal mounting frame that covers the front opening of the body, a metal middle frame for attaching the decorative plate to the front of the mounting frame, and this middle frame is attached to the above mounting frame. It has a metal plate screw that screws into the frame to fix the inner frame, and a decorative cover that is attached to the front of the inner frame, and the threaded part of the mounting frame to which the plate screw is screwed is made of synthetic resin. A dimmer switch characterized by: (2) A contact mechanism block that opens and closes the contacts by operating a handle, a printed circuit board block equipped with a dimming unit that controls the lighting load by the output of the contact mechanism block, and a body that houses both of the above blocks; A metal mounting frame that covers the front opening of the body, a metal middle frame that attaches the decorative plate to the front of the mounting frame, and this middle frame is screwed onto the above mounting frame to fix the middle frame. It has a metal plate screw and a decorative cover attached to the front surface of the inner frame, and a heat dissipation fin is formed on the heat dissipation plate of the printed board block,
This dimmer switch is characterized in that the heat dissipation fins are exposed to the outside through a notch cut out in the body. (3) A contact mechanism block that opens and closes the contacts by operating the handle, a printed circuit board block equipped with a dimming unit that controls the lighting load by the output of the contact mechanism block, and a body that houses both of the above blocks; A metal mounting frame that covers the front opening of the body, a metal middle frame that attaches the decorative plate to the front of the mounting frame, and this middle frame is screwed onto the above mounting frame to fix the middle frame. 1. A dimmer switch comprising a plate screw and a decorative cover attached to the front surface of an inner frame, the plate screw being made of synthetic resin. (4) A contact mechanism block that opens and closes the contacts by operating the handle, a printed circuit board block equipped with a dimming unit that controls the lighting load by the output of the contact mechanism block, and a body that houses both of the above blocks; A metal mounting frame that covers the front opening of the body, a metal middle frame that attaches the decorative plate to the front of the mounting frame, and this middle frame is screwed onto the above mounting frame to fix the middle frame. 1. A dimmer switch comprising a plate screw and a decorative cover attached to the front surface of an inner frame, the mounting frame having heat dissipation fins formed thereon.
